"""
Date strings to translate per each language for display and parsing.

__main__
--------

Run this code with the appropriate ``LANG`` and ``LC_DATE`` set for your target
language, in order to generate the .po snippets initialized with the strings
from your locale (from the deprecated data provided in _locale).

E.g., for French::

    LANG=fr_FR.utf8 LC_ALL=fr_FR.utf8 GRAMPS_RESOURCES=$PWD python -m gramps.gen.datehandler._datestrings

Then merge the output into your language's .po file, and further modify the
strings as needed. Then remove the strings from your language's
:class:`DateParserXX` and :class:`DateHandlerXX` classes.
